Biologists uncover the secrets of evolutionary change
University of Sheffield

Significant evolutionary changes happen gradually as opposed to in dramatic ‘monster’ steps, biologists have discovered, answering the long-debated question as to how game-changing innovations like flight, vision, and the bearing of live offspring came to be.

Evolution is not as random as previously thought, finds a new study
University of Nottingham

A groundbreaking study has found that evolution is not as unpredictable as previously thought, which could allow scientists to explore which genes could be useful to tackle real-world issues such as antibiotic resistance, disease and climate change.

A Mathematical Model Connects the Evolution of Chickens, Fish and Frogs
University of California San Diego

One of the most enduring questions of life is: How does it happen? One line of scientific inquiry lies in understanding gastrulation — the stage at which embryo cells develop from a single layer to a multidimensional structure. New research suggests that the same physical principles behind multicellular self-organization may have evolved across vertebrate species.
